IMPROVEMENT IN CARBURETING APPARATUS.

Specification forming part of Letters Patent No. 153,872, dated `August 4, 1874; application led J une 18, 1874.

To all 'whom t may concern:

Be it known that I, EDWARD P. WHEELER, of Corinth, in the county of Alcorn and State of Mississippi, have invented certain new and useful Improvements in Carbureting Apparatus; and do hereby declare that the following is a full, clear, and exact description thereof, Whichwill enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The nature of my invention consists in the construction and-arrangementof a machine for the manufacture of illuminating-gas.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- A Figure l is a section of my gas-machine through the line as w, Fig. 2. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal section ofthe air-pump. Figs. 4 and 5 represent a porous partition used in the gasolinetank. Fig. 6 represents a mercury-valve used between the pump and oil-tank.

My gas-machine consists essentially of three partsan air-pump, A, an oil-tank, B, and a gas-holder or gasometer, O. The gasometer is constructed in the ordinary manner, and connected from near the bottom with the top of the oil-tank B, by means of a pipe, D. The oil-tank B and air-pump A are also connected by means of a pipe, E, which passes from the center of the pump through the top ofthe oiltank downward to near the bottom thereof. The pipes D and E may each be made in one or more sections, as required, and certain parts of each pipe be made iiexible, so as to accommodate the machine to any location convenient for its reception. rIhe pipe E, connecting the pump A with oil-tank or gasoline drum B, has a U-shaped part, a, in which a certain quantity of quicksilver orvmercury, b, is placed to form a valve. Above the mercury-valve b, toward the oil-tank, the pipe a is enlarged, as Ashown at d, so that the mercury can spread, and not be carried over into the oil-tank. In passing air in the opposite direction into the small tube the mercury will rise higher and act as a check-valve in that direction. The mercury takes the place of an air-tight cock. No matter how rough the pipe may be, this valve will be air-tight at all times against a certain pressure, which can be increased at Will by adding mercury, or by changing the construction of the tube. The air-pump A is provided with perforated inlets ff, to exclude everything but air, but most especially to eX- clude fire.

In the gasolinetank B, above the gasoline or other hydrocarbon liquid used, is placed a porous sand-holder, G, to take up all surplus gasoline taken up in vapor, and prevent it being carried over into the pipes or gasometer. This makes a porous partition, on which or between which is placed sand that all vapor and gas must pass through before entering the gasometer or going to the consumer.

The sand-holder may inv some cases be placed in the pipe D above the oil-tank, if so desired.

The pipes D and E above the tank are connected by a pipe, h, which is used in case the gas is too strong to pass pure air into the gasometer by shutting oft' the cocks to the gasoline-tank.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination of the air-pump A, oiltank B, and pipe E, with mercury-valve a. b d, as and for the purposes herein set forth.

2. The combination of the air-pump A, oiltank B, pipe E, with mercury-valve a b d, pipe D, and gasometer C, as and for the purposes herein set forth.

3. The oil-tank B, with porous holder G, filled with sand, and the pipes E and D, in combination with mercury-valve a b d and airpump A, having perforated inlets f f, all constructed and arranged as and for the purpose specified.

In testimony that I claim the foregoing as my own invention I aflix my signature in presence of two witnesses.

EDWARD P. WHEELER.
